Parameters
-ClusterConnectionString
Specifies an array of cluster connection strings for the cluster to which you want to add the device drivers.
The value format is host1,host2,host3.
If you do not specify the ClusterConnectionString parameter, this cmdlet uses the connection string on the head node that the CCP_CONNECTIONSTRING environment variable specifies.
To set this environment variable, run the following cmdlet: Set-Content Env: CCP_CONNECTIONSTRING \<head_node_name\>.
This parameter was introduced in HPC Pack 2016.

Notes
- After you create a new node group, you can add nodes to the node group by using the Add-HpcGroup cmdlet. To change the name or description of the group after you create it, use the Set-HpcGroup cmdlet.
- You must be a cluster administrator to run this cmdlet successfully.
